Data source

The data is collected and reported on a calendar-year basis (January 1 to December 31). This is consistent with the practice in other international registries that report on end-stage organ failure.

As a result, international comparison reporting is possible.

Data coverage

Patients are tracked from the first treatment stage (dialysis or transplantation) to the time of death, unless they are lost to follow-up.

Only treatments provided in Canada are included in CORR reports. CORR also captures data about patients transferred outside of Canada when those facilities report the transfers. This makes it possible to record continuity of care.

Information on organ donors is linked to information about those who receive the organs.
